I would like to remotely monitor temps in my fridge. My preference would be to get push notifications on alarm, and be able to get remote access to current temps. Anyone got recommendations on reliable brands/models?
I don't use any HA equipment.There are some sensors that have remote probes that way you'll have more reliable transmission.
Which of the following do you currently use in your HA: zwave, zigbee, bluetooth / bluetooth low energy.
I failed to mention in post #4 that the Shelly devices have an app for smartphones and a free cloud for remote control and monitoring.I don't use any HA equipment.
I have doubts that the Shelly H&T sensor battery will perform well long-term in a freezer. The sensor does, however, support being externally powered.The Shelly H&T is Wi-Fi, has 18 mo. battery life
Yes, they offer good balance of run time vs common cells anyone can buy anywhere. But, as they use larger AAA cells the physical size is well defined and can't be smaller. Those that use smaller coin cells (I haven't seen) can push the same level of battery run time.YoLink batteries last 5 years and they are all the same, the common AAA size.
I'm assuming the yolink also sends the same based on a timed interval. Otherwise how would you ever be able to track the metrics over a period of time where the temperature is stable / doesn't fluctuate??Yolink signals are on demand and do not suffer from this delay you mention.
Neither do any of my z-wave sensors. They all respond within an average of 1 second, maybe sometimes 2 seconds (that I get the actual notification)
Perhaps less of a concern with the Shelly H&T sensor?Probably the only thing that keeps me from deploying a whole bunch of these battery operated sensors is the fact my other goals are to reduce my RF in and around the home
